Your 5-Point End-of-Year Financial Checklist

It's that time of the year again -- when we not only start counting down toward Jan. 1, but also begin crossing critical items off our financial to-do lists. So if you'd like to end 2017 on a financially strong note, here are a few moves to start working on today.

1. Max out your 401(k), or get as close as possible

The benefit of working for a company with a 401(k) is the opportunity to save far more for retirement than you can with an IRAs alone. Unfortunately, most workers don't take full advantage of this option. According to Schwab, only 15% of participants max out their 401(k)s. If you aren't one of them, then now's the time to get moving.

The more you contribute to your 401(k) this year, the greater a tax break you'll get. Currently, workers under 50 can put up to $18,000 a year into a 401(k). Older workers 50 and over get an even more generous allowance -- a $6,000 catch-up provision increases this limit to $24,000.

What will maxing out your 401(k) do for your taxes? Let's assume you're in your 40s, and that your effective tax rate is 30%. If you put $18,000 into your 401(k), you'll shave $5,400 off your IRS bill.

Keep in mind that it often takes a pay cycle or two to change your 401(k) allocation, so if you're looking to ramp up in December, now's the time to act. Once 2017 comes to a close, you can no longer contribute to your 401(k) for the year (though you can, of course, get started on your 2018 contributions).

2. Review your investments

Whether you're saving in an IRA or 401(k), the end of the year is a good time to examine your holdings and see if it pays to do some portfolio rebalancing. This especially holds true if you're getting closer to retirement, and expect to start selling off investments in the coming years.

Ideally, your portfolio should be fairly stock-heavy if you're younger, and contain a healthy mix of stocks and bonds when you're older. Furthermore, your investments should be spread out across a variety of industries; you don't want the bulk of your cash in a single sector, lest it take a dive.

Also, be wary of the way high-performing investments may unbalance your portfolio. Just because a particular stock or sector has a few good years doesn't mean that pattern well continue indefinitely. If you see that you're heavily invested in a single industry due to its recent growth, it might pay to take some gains, sell off part of that position, and put more money into a different sector. Remember, if you're talking about investments held in an IRA or 401(k), you won't pay taxes on those gains right away, and if you have a Roth-style account, you won't pay taxes on them at all.
